  • C-plane processing device 11 transmits the cell information necessary for the started-up U-plane processing devices 12.
  • Each of U-plane processing devices 12 1 to 12 N acquires the cell information from C-plane processing device 11 when starting up, and thereafter operates by making use of the acquired cell information.
  • Each of NodeBs 13 1 to 13 M covers at least one cell and is connected with mobile stations through a radio interface.
  • NodeBs 13 1 to 13 M terminate the radio interfaces and transmit user data to U-plane processing devices.
  • Router 14 interconnects between C-plane processing device 11, U-plane processing devices 12 1 to 12 N and CN 15 and handles the routing of user data and control signals.
  • CN 15 is a network for providing circuit switching and packet switching services.
  • Fig. 3 is a sequence diagram representing the operation of the U-plane processing device in the RAN of the present embodiment when the U-plane processing device starts up.
  • U-plane processing device 12 completes startup as a stand-alone device (step 101)
  • U-plane processing device 12 sends a notice of startup completion to C-plane processing device 11 (step 102.)
  • the C-plane processing device 11 sends necessary items of the cell information to the U-plane processing device 12 (step 103.)
  • U-plane processing device 12 When receiving the cell information, U-plane processing device 12 sends a reply to C-plane processing device 11 (step 104) and deploys the cell information received from C-plane processing device 11 in its own memory table (step 105.)
  • the memory table is formed, for example, in nonvolatile memory.
  • Fig. 4 is a diagram illustrating an aspect of the memory table on which cell information is deployed.
  • Fig. 4(a) it is shown that the cell information of cell #1- and cell #2 has been set in the memory table before deployment of the cell information received from C-plane processing device 11.
  • the cell information of cell #3 is added and LAC of cell #2 is changed from E' to E, as shown in Fig. 4(b) .
  • U-plane processing device 12 correctly grasps the information about the cells and NodeBs to be placed under control of U-plane processing device 12 itself and is placed in the state that is able to perform the NBAP processing and to decide the destination cell for paging.
  • the RAN did not attain a call-enabled state.
  • U-plane processing device 12 establishes a Layer-2 link to NodeB 13 by reference to the cell information (step 107.)
  • step 108 U-plane processing device 12 and C-plane processing device 11
  • cell architectures are established (step 108)
  • links of common channels are set up (step 109)
  • broadcast information is set (step 110)
  • the call-enabled state is established in the entire RAN system (step 111).

  • U-plane processing devices 12 1 to 12 N individually obtain necessary cell information from C-plane processing device 11 during start-up, U-plane processing devices 12 1 to 12 N need, by default, only minimal information items required for booting up, and do not require any individual setting when manufactured or before installation thereby promoting the efficiency of the work operation.
  • U-plane processing device 12 when receiving a request for paging transmission from C-plane processing device 11, U-plane processing device 12 consults the memory table shown in Fig. 4 referring to LAI (Location Area Identity) that is included in the request for paging transmission and decides on the NodeB and cell to transmit the paging.
  • LAI is represented by MCC, MNC and LAC in Fig. 4 , and thus U-plane processing device 12 decides to send the paging to the cell identified by the same LAI.
  • LAI refers to the identifying information of the region of the paging, i.e. the area in which broadcast paging is executed.
  • C-plane processing device 11 notifies the cell information to U-plane processing device 12, when receiving a notice of the completion of boot up from U-plane processing device 12, it is also permissible that U-plane processing device 12 requests the cell information from C-plane processing device 11 based on need independently of the completion of boot up. Thereby, U-plane processing device 12 can acquire the information from C-plane processing device 11 as need arises, and thus can maintain the state of holding appropriate information without resetting.
  • the cell information is notified from C-plane processing device 11 when U-plane processing device 12 is booted up
  • the cell information is notified from C-plane processing device 11 based on the voluntary decision of C-plane processing device 11 independent of the boot up of U-plane processing device 12.
  • notification of the cell information can be supplied to all or a plurality of U-plane processing devices 12 1 to 12 N at one time, or alternatively can be supplied individually to U-plane processing devices 12 1 to 12 N .
  • the present invention is not limited to such procedures. If the appropriate cell information is deployed in nonvolatile memory in U-plane processing device 12, then acquiring the cell information at the time of boot-up is not necessarily needed.
  • U-plane processing device 12 requests the cell information from C-plane processing device 11, for example, in the case when U-plane processing device 12 is boot up without having the cell information stored in the memory table, and does not request the cell information from C-plane processing device 11 if U-plane processing device 12 is booted up having the cell information stored in the memory table. Further, if U-plane processing device 12 is rebooted on account of a serious failure, U-plane processing device 12 requests the cell information to C-plane processing device 11 even if the cell information is present on the memory table.
